Card reader, microcontroller, wifi or ethernet, and some Big Ass Relays. The list of authorized cards is sent out to the stations when it is updated. The card must be present in the reader, and, if valid for that station, turns on the relays placed in the power line. Pull out the card, relays turn off. Sure, you can hack it by taking the box apart and bypassing the relays, but by the time you get done doing that, someone else will have come in and asked wtf is going on. Not to mention the cameras. <br><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">Komradebob<br><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jun 16, 2015 at 2:09 PM, Pete Prodoehl <span dir="ltr"><<a href="mailto:raster@gmail.com" target="_blank">raster@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>
Any info on how you are doing the system? We've discussed using RFID for machine access multiple times but no one has stepped up to design (or build, or fund) a system yet.<br>

At the CoG, we are using an off the shelf card system but are implementing our own rfid system for the new building. Cost and flexibility are the motivations. We need to control >10 doors, >10 locking cabinets, and a similar number of machine tools, 3d printers, etc.<br>
<br>
Nothing on the market will drive that many doors that for under $$$$. The building system that was quoted handled 12 doors and was >$30k. And it went up exponentially from there. Not to mention it was a closed system so we could not tie it into our CRM/member management system.<br>
<br>
The result is a system based on COTS hardware (Commercial door strikers, magnetic locks, card readers, biometric scanners, TiVa C and Ethernet relay boards) and an open API.<br>

The Red Mountain Makerspace has been using a commercial APT system in March, in combination with keyed locks.<br>
<br>
Yes, this is not terribly hackerish, but we needed to get infrastructure in place in a relatively short period of time to deal with some real security concerns. We're in an old building in a transitioning neighborhood. We need to grow our org as quickl to address real community needs for tech education, exploration and community development, so we've chosen to pay for services that will take time and skill to develop, while using the inhouse talent pool to complete tasks within their existing skillsets.<br>
<br>
Going with a commercial solution for the next few years allows us to focus on growing our introductory circuitry, 3D printing, CNC, open source and programming offerings and to support development of the local tech community. Our plan is to switch to RFID cards tied to membership dues payment within the next nine months. (we'll probably get it done sooner, but we are practicing allowing for the worst and working towards the best possible outcomes).<br>

Here's a good podcast that covers a related topic: <a href="http://99percentinvisible.org/episode/perfect-security/" rel="noreferrer" target="_blank">http://99percentinvisible.org/episode/perfect-security/</a><br>
<br>
tl;dr: "It’s not just locks that keep us safe—it’s the existing social order."<br>

A hackerspace I belong to has probably hit the point of needing<br>
an alarm and access control system. I'm wondering what good<br>
solutions have been created - what the "state of the art" is in<br>
hackerspace security these days.<br>
<br>
<a href="https://wiki.hackerspaces.org/Doorlock" rel="noreferrer" target="_blank">https://wiki.hackerspaces.org/Doorlock</a><br>
<br>
It'd be awesome if that were updated with any new projects - and<br>
if some of the existing writeups could be updated or better<br>
documented; a number of them say "this writeup needs to get<br>
updated" or the writeup is super sparse. This is a very common<br>
and basic need, so more info/guidance would be very beneficial.<br>
Not just what people have made, but tradeoffs, lessons learned,<br>
mistakes made, etc.<br>
<br>
Also: why do so many of these hackerspace access control systems<br>
use RFID / proximity cards? Hackerspace people are among the<br>
most likely to know how laughable security is with them, yet so<br>
many hackerspaces use them? It's...weird.<br>
